Benefits of technology

The invention allows for appropriate responses based on the data used to answer queries from a control device. For example, when a control device asks about a temporary change in a setting, the invention can return the original value. When the control device asks about font data, the invention can answer based on the data in the code page that holds the font data. This helps to improve the efficiency and accuracy of responding to queries from a control device.

Problems solved by technology

However, this configuration also requires storing information for managing the relational database (such as the address of each field in the storage area, and information about the relationships between the data stored in each field), unnecessarily requires providing a corresponding storage area, and thus creates problems with efficient use of nonvolatile memory.

embodiment 1

[0050

[0051]FIG. 1 is a block diagram showing the functional configuration of a recording system 1 according to a first embodiment of the invention.

[0052]The recording system 1 includes a host computer 10 (control device) and a printer 11 (recording device), and is a system for recording on a recording medium with the printer 11 as controlled by the host computer 10. More specifically, the host computer 10 and printer 11 in the recording system 1 according to this embodiment of the invention work together to print receipts. The operation of the host computer 10 and the printer 11 when producing a receipt is described below.

[0053]As shown in recording system 1, the host computer 10 has a host-side controller 15, a host-side display unit 16, a host-side input unit 17, a interface 18, and a host-side storage unit 19.

[0054]The host-side controller 15 centrally controls other parts of the host computer 10, and includes a CPU, RAM, ROM, and other peripheral circuits. The host-side controll...

embodiment 2

[0121

[0122]FIG. 6 is a block diagram showing the functional configuration of a recording system 101 according to this embodiment of the invention.

[0123]The recording system 101 is used in retail stores such as supermarkets and convenience stores, and is a system having at least a function for issuing receipts for bill and purchase payments by customers visiting the store, and as shown in FIG. 6 includes a host computer 110 (control device), POS server 111, and printer 112 (recording device).

[0124]The POS server 111 is connected to and communicates with the host computer 110 over a network, and stores data for information required to print receipts, including product code, name, and price information for products sold by the store, in a database. In order to issue a receipt, the host computer 110 references the database stored on the POS server 111 as needed to acquire the required information.

[0125]The host computer 110 has a host-side control unit 115, host-side display unit 116, h...

Abstract

Queries from a control device are answered based on the data actually used. When a control command is received from a host computer, the recording control unit of a printer changes a value related to the recordable area stored in a temporary storage area according to the content of the control command, uses the new value to record in the recordable area, and returns the new value when queried by the host computer about the setting for which the value was changed.

Description

BACKGROUND[0001]Priority is claimed under 35 U.S.C. §119 from Japanese patent application nos. JP 2012-069210 filed on Mar. 26, 2012 and JP 2012-079660 filed on Mar. 30, 2012, which are hereby incorporated by reference in their entirety.[0002]1. Technical Field[0003]The present invention relates to a recording device that can connect to a control device, and to a method of controlling the recording device.[0004]2. Related Art[0005]Recording devices (print control devices) that store the values for various recording-related settings, and execute recording-related operations while referring to these settings, are known from the literature. See, for example, Japanese Unexamined Patent Appl. Pub. JP-A-2008-203926. Control devices (such as host computers) that control such recording devices generally have a function for querying the recording device about these settings.[0006]Recording devices (serial printers) that store font data and can record characters (text) based on the font data ...
